LYNC servers use topology builder to build the topology. Put the topology information over SQL server

called CMS (Central Management Store)

Topology builder is the tool installed to architect your LYNC environment. Using topology builder you are

going to define pools, Sites, Server, Backend SQL DB server, what are the other features you are

required etc

The process of Defining the topology inside the topology builder is typically referred as authoring the

topology.

AD, SCHEMA and FOREST Preparation

Then prepare the AD schema to add new Objects and attribute classes for the LYNC

environment.

Prepare AD Forest for create the universal security groups and roles to provide role based access

control for the LYNC Environment.

We need prepare all the domains that are going to host or contain any of the LYNC server rolesor clients. This process will modify the access control list.

Forest and domain functional level should be windows 2003 or higher.

After completing all the above requirements and authoring the LYNC topology you need to publish the

topology in a backend SQL server database. Enterprise edition requires a full working version of SQL 64

Bit server Database.

Before installing LYNC you need to add the first server in the AD domain.

Every LYNC server in your environment is going to get a local copy of the CMS (Read only copy) (Central

Management Store). This database containing the topology and policy configuration in your

environment.

In an enterprise edition of LYNC there will be a backed SQL server that hosts the CMS. Every server will

get a local coy, a read only copy. To install LYNC you need to retrieve a local copy of topology from CMS.

Your LYNC server requires a certificate, possibly multiple certificates depending on the server roles that

you are going to deploy.

After installing the Microsoft LYNC server you can verify the installation from the LYNC control panel and

make sure the services corresponding the roles are started.

SQL server

In enterprise Edition of LYNC deployment we will have a central copy of CMS in the backend SQL server.

We deploy a topology on the SQL server where the CMS run.

Database Server Requirements:


2/12

SQL server 2008 R2 Enterprise 64 Bit / SQL server 2008 R2 Standard 64 Bit

SQL server 2012 Standard 64 bit

SQL server should be installed with the latest Service Pack

SQL server will be used as a backend database for front end pool, Persistent Chat server

Database, Archiving and monitoring Server database.

Each of the LYNC servers will contain a local copy of the CMS database and LYNC will install a

local copy of SQL server 2012 Express edition 64 bit on all of the LYNC servers.

LYNC server also support SQL server Mirroring (New feature with 2013).

Preparing the infrastructure and systems.

Memory Requirements for Enterprise edition front end server 32 GB, 2.26 GHZ Hex core

72 GB free space for OS and database local copies

Recommended to install OS in a RAID1 (Mirroring)

File Server Requirements

Enterprise edition of LYNC server requires a file server( File server share).

The file share is used by the enterprise edition of servers within a pool to share content across

pool such as application content.

Enterprise edition of LYNC server requires shared file storage for the servers participating within

the pool. With full control to the administrator.

This file share can be in the SAN, DAS, Clustered file share( for high Availability)

OS Requirements for LYNC server( on All the servers)

Windows 2008 R2 SP1 or higher Powershell V3 (Windows Management Framework PowerShell V3)

.NET framework 4.5 or later( if you are installing 2012 server After the installation of .NET

Framework 4.5 install HTTP server activation from server manager, this is a server manager

feature.)

Windows Identity Foundation

IIS

Windows Desktop Experience.

Windows media format runtime.

Microsoft Message Queuing ( This component is for Persistent chat, Archiving and monitoring

support)

Certificate Infrastructure requirements

Internal DNS Requirements


3/12

Name resolution for pool. All the devices in the pool will be normally connected to a hardware load

balancer and a virtual IP (Single Virtual name against multiple IPs) willbe assigned for all the servers in a

pool.

Eg:

LYNCPool.Costi.org 192.168.5.10



Defining LYNC server 2013 Topology

CMS (Central Management Store)

MS has moved away from storing the LYNC configuration information in the Configuration partition of

AD to SQL server. This is mainly because of reducing AD replication delay due to more data stores in AD

database.

Now we are using SQL server to store the configuration information about the LYNC configuration.

The database is called xds.mdf

Every LYNC server in the environment will store a local copy of topology information in the local SQL

database ( Express Edition of SQL installed with LYNC)

CMS database contains:

Topology Information

Configuration Settings

Policies

This information is replicated among other servers in the environment.

Your servers will use a share in the format \\servername\xds-replica. This share is used for replicating

xds database content among all the servers.

Defining the topology in the topology builder.

Topology builder is a tool that we will use to define the sites, Pools, servers( servers participating in front

end pool, mediation server configuration, gateway, etc)

SIPis the Session Initiation Protocol. In IP and traditional telephony, network engineers have always

made a clear distinction between two different phases of a voice call. The first phase is "call setup," and

includes all of the details needed to get two telephones talking. Once the call has been setup, the

phones enter a "data transfer" phase of the call using an entirely different family of protocols to actually

move the voice packets between the two phones. In the world of VoIP, SIP is a call setup protocol that

operates at the application layer.

in addition to simple telephone calls, SIP can also be used to set up video and audio multicast meetings,

or instant messaging conferences.

While defining Topology you need to specify the SIP domain,

Then Define the first Site Name ( here you can specify the site name as College or Brampton.

Front End pool FQDN (Here we are choosing whether we are using Standard edition or enterprise

edition of Lync.


5/12

When you choose enterprise edition you need to provide the name of the servers in the pool. If you

choose standard edition you dont have the option to provide a pool name. you can add up to 20 serversin the pool.

Next will be the features that you are going to use in your environment. Instant messaging and presence

are always enabled. When you choose archiving it will enable exchange server integration.


6/12

Next is to choose to collocate the mediation server in the front end server. This is the server that

communicate with your gateway(IP/PSTN gateway)

Next is to define SQL server store


7/12

Nest is to define a file share for XDS


8/12

Next is for providing the web services URL (for internal and external)

Next is to specify the office 2013 web app server. This enables users to share and view

PowerPoint presentation during meetings with enhancements including animations, slide

transitions, embedded video and the ability for users to independently navigate slides.

Next is to define the Archiving SQL server store.


9/12

Define the Monitoring SQL server store.

After completing the topology builder you can verify or modify the parameters as shown

below.


10/12

Right click on enterprise Edition front end pool pool name properties

Once you complete the topology using topology builder you need to publish it in CMS. Also you

can edit the existing topology. When you are editing you are not editing the working copy. After

you complete the editing you need the republish it to effect the changes.
